The singer introduced his son, Silas Randall Timberlake, in a super sweet snap on Instagram over the weekend. (Check out that top-tier brand of adorable in the photo above!)

"The Timberlakes are ready!!! GO GRIZZ!" Justin captioned the photo of Jessica cradling their baby boy, who is outfitted in the teeniest of Memphis Grizzlies uniforms. "#GritNGrind #Playoffs #BabyGrizzROAR."

The happy couple, who announced the arrival of their "greatest creation yet" earlier this month, have been beyond ecstatic in their role as first-time parents.

Though rumors had been circulating for quite some time, the former boy bander officially confirmed the news that he and the 7th Heaven actress were expecting their firstborn in January 2015, on Justin's 34th birthday.

He also couldn't contain himself when he accepted the Innovator Award at the 2015 iHeartRadio Music Awards, telling the audience: “I can't wait to see our greatest creation yet. Daddy’s heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on!”

The A-list pair, who married in October 2012, kept their baby boy's name within the family. According to PEOPLE, Silas' first name comes from Justin's late grandfather's middle name, while his middle name, Randall, is Justin's own middle moniker, as well as the singer's father's first name.
